Quantum computers are computing systems that process information leveraging quantum mechanical effects. These computers rely ...

Two-dimensional projection of a quantum spherical code composed of two copies (black and red) of the four complex dimensional Witting polytope. This code can correct up to five photon losses of any ...

“The vision was to build a useful, large-scale quantum computer that could harness quantum mechanics — the ‘operating system’ of nature to the extent we know it today — to benefit society by advancing ...

Scientists have designed a physical qubit that behaves as an error-correcting "logical qubit," and now they think they can scale it up to make a useful quantum computer using a few hundred. When you ...

China is racing to harden its quantum ambitions on two fronts at once, pairing more powerful quantum processors with new ...

The first IBM Quantum System Two, located in Yorktown Heights, New York, has begun operations with three IBM Heron processors and supporting control electronics. The consensus among industry analysts ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive.

Sitting in an office at QuEra Computing’s Boston headquarters, Yuval Boger was talking about the recent advancements made in quantum computing that are driving the chorus around an accelerated the ...

For more than a decade, the world of digital currency has been built on a single foundation: the blockchain. This complex, code-based system of distributed ledgers was a revolutionary approach to ...

If you want to tile a bathroom floor, square tiles are the simplest option — they fit together without any gaps in a grid pattern that can continue indefinitely. That square grid has a property shared ...
